Abstract (en)

[origin: US5855942A] A method and composition for enhancing retention of carbon dioxide in carbonated bottled beverages indicates the addition of a carbonic acid ester such as propylene carbonate, 1,3-butylene carbonate, diethyl carbonate, neopentylene carbonate and propylene carbonate or mixtures thereof. The carbonic acid ester in the aqueous medium of the beverage undergoes slow hydrolysis thereby releasing CO2 to maintain the CO2level in the container.
